Which reflection rule, if any, can be used to prove that rectangle a(-8, -3), b(-2, -3), c(-2, -6), d(-8, -6) and rectangle a'(8, -3), b'(2, -3), c'(2, -6), d'(8, -6) are congruent? a) (x, y) → (-x, y) b) (x, y) → (x, -y) c) (x, y) → (-x, -y) d) the rectangles are not congruent.

Find the solution set of this inequality. enter your answer in interval notation using grouping symbols. |8x-4| ≤ 12

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
